Daejeon대전광역시

Daejeon is a major science and transit hub in central Korea, home to Expo Park, the Daedeok Innopolis research district, hot springs, and the beloved Sungsimdang bakery.

Population

About 1.44 million people (2026), South Korea's fifth-largest city.

Fun fact

Sungsimdang, now one of Korea's best-known bakeries, was founded in Daejeon in 1956 after its founder's family got stranded when their train broke down at Daejeon Station — the bakery went on to bake bread for Pope Francis during his 2014 visit to Korea.

Daejeon on the map

Daejeon is a major science and technology city in central South Korea, a KTX hub built around a dense cluster of national research institutes and universities.

History

Daejeon's native name, Hanbat, means "great field," reflecting its origins as a rural farming area through the Three Kingdoms, Goryeo, and Joseon periods, when it was a minor settlement rather than a major town. Its transformation began with the Gyeongbu railway line, which reached the area in 1904; the new Daejeon Station drew migrants and merchants, and the settlement grew rapidly around the rail junction. Japan's colonial administration merged surrounding counties into Daejeon in 1914, and after the Korean War the city kept expanding as a transportation and administrative center, reaching Metropolitan City status in 1989. From the 1970s the government began developing what is now Daedeok Innopolis as a hub for national research institutes, and in 1997 several national government agencies relocated to a new Government Complex in the city. Daejeon's 1993 Expo further cemented its identity as Korea's science and technology city.

Highlights

  • Expo Science Park and Hanbit Tower, built on the grounds of the 1993 Daejeon Expo and anchored by the National Science Museum.
  • Yuseong Hot Springs, a natural hot-spring district with public baths and spa hotels dating back decades.
  • Hanbat Arboretum, the largest artificial arboretum in Korea, with themed gardens near the Government Complex.
  • Bomunsan Mountain Park, a city park since 1965 combining hiking trails, temples, and the O-World zoo and amusement park.
  • Sungsimdang, the flagship store of Daejeon's famous bakery chain, founded in 1956 near Daejeon Station.

Food

Daejeon's best-known food name is Sungsimdang, a bakery founded in 1956 whose fried soboro bread helped make it one of Korea's most recognized bakery brands — its flagship store near Daejeon Station is itself a stop on many visitors' itineraries.

Getting there

Daejeon is one of Korea's best-connected cities: KTX high-speed trains reach Daejeon Station from Seoul in about 50 minutes, and Seodaejeon and Daejeon Complex bus terminals both run frequent intercity buses to Seoul and beyond.

How long

As a major city with sights spread across a wide urban area, Daejeon works well as a day trip from Seoul thanks to the fast KTX connection, though an overnight lets you add Yuseong Hot Springs or a fuller look at the Daedeok research district without rushing.
